Since its initial description as an antiviral, it has become clear that Interferon-gamma (IFN-gamma) has potent immunoregulatory and cell growth regulatory activities. As a result of these additional activities, it is now apparent that IFN-gamma plays a major role in regulation of bacterial infections. IFN-gamma can be both induced by bacteria and bacterial products; endogenous IFN-gamma production has been shown to play a protective role in the natural host response to several bacterial infections; and administration of exogenous IFN-gamma is effective in the prevention and treatment of bacterial infections in numerous animal model systems. Although it is now clear that IFN-gamma plays a role in regulation of bacterial infections, the mechanisms of its anti-bacterial effects in vivo remain to be established due to the pleiotropic nature of IFN-gamma activity.

Monitoring wound infection and providing appropriate treatment are crucial for achieving favorable outcomes. However, the time-consuming nature of laboratory culture tests may delay timely intervention. To tackle this challenge, a simple yet effective HDG hydrogel, composed of hydrogen peroxide (H₂O₂), dopamine, and GelMA polymer, is developed for the ultrafast detection and treatment of Staphylococcus aureus (SA) infections.

Background: Oral infectious diseases, such as dental caries, periodontitis and periapical periodontitis, are often complicated by causative bacterial biofilm formation and significantly impact human oral health and quality of life. Bacteriophage (phage) therapy has emerged as a potential alternative with successful applications in antimicrobial trials. While therapeutic use of phages has been considered as effective treatment of some infectious diseases, related research focusing on oral infectious diseases is few and lacks attention.

Background: Nocardia are widely present in nature and considered opportunistic pathogens. They can result in hematogenous spread infection through the ruptured skin or respiratory tract when the host's immune system is compromised. Currently, 119 species of Nocardia have been identified, with 54 capable of causing infections in humans.

Chronic infections represent a significant global health and economic challenge. Biofilms, which are bacterial communities encased in an extracellular polysaccharide matrix, contribute to approximately 80% of these infections. In particular, pathogens such as Pseudomonas aeruginosa and Staphylococcus aureus are frequently co-isolated from the sputum of patients with cystic fibrosis and are commonly found in chronic wound infections.

Congenital neutropenia (CoN) is a heterogeneous group of inborn errors of immunity (IEI) characterized by recurrent infections and early onset of neutropenia (NP). This study aimed to investigate the demographic and clinical data of children with CoN and idiopathic neutropenia (IN) in Morocco. We performed a retrospective study of patients with CoN and analyzed the clinical and laboratory findings of patients with CoN and IN diagnosed between 1999 and 2018 in a clinical immunology unit of a large pediatric hospital.
